A negative clamp is the opposite of this—this clamp outputs a purely negative waveform from an input signal. A bias voltage between the diode and ground offsets the output voltage by that amount. For example, an input signal of peak value 5 V (V INpeak = 5 V) is applied to a positive clamp with a bias of 3 V (V BIAS = 3 V), the peak output ...
A simple diode clipper can be made with a diode and a resistor. This will remove either the positive, or the negative half of the waveform depending on the direction the diode is connected. The simple circuit clips at zero voltage (or to be more precise, at the small forward voltage of the forward biased diode) but the clipping voltage can be ...
This simple diode clamp will clamp the negative peaks of the incoming waveform to the common rail voltage. A diode clamp circuit can take a periodic alternating current signal that oscillates between positive and negative values, and vertically displace it such that either the positive or the negative peaks occur at a prescribed level. The ...
A transient-voltage-suppression diode can respond to over-voltages faster than other common over-voltage protection components such as varistors or gas discharge tubes. The actual clamping occurs in roughly one picosecond, but in a practical circuit the inductance of the wires leading to the device imposes a higher limit. This makes transient ...
The saturation clamp supply needs to supply substantial current. [10] In contrast, the Baker clamp reduces the transistor base current rather than supplying more collector current. Another clamp circuit uses a single diode clamp. [9] It reduces base drive as the transistor nears saturation, but it uses a resistor divider network.
In these applications, stabistors offer improved dynamic impedance (voltage change vs. current) than low voltage zener diodes where tunneling instead of avalanche current is dominant. [1] [2] Other typical applications include bias stabilization in class-AB output stages, clipping, clamping, meter protection, etc. [3]

English: What it does is use diode clamps to eliminate over and undershoot. The "trick" is that instead of clamping to +5 and GND they clamp to the output of two regulated voltages. This allows the clamping diodes to turn on earlier and is therefore better at eliminating overshoot and undershoot.
